FEED-WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent N0. 615,830, dated December A13, 1898. Application filed J'une 28,1897. Serial No. 642,598. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES E. FERREIRA, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Feed-Water Heaters and Purifiers, of which the following is a specification.

My invention has relation to a feed-Water heater and purifier; and its obj'ect is to provide such a device embodying many advantages, besides being simple in its construction and arrangement and reliable in its operation.

One of the main objects is to provide for the maintenance of different Water-levels,-as required in summer and Winter or at other times. These heaters are frequently used in large cities in low basements, and when the steamheating system, for instance, is in operation in winter it is necessary that the water-line shall be below the lowest radiator to prevent its flooding. Consequently for winter service I provide a low-water line.

My invention embodies other advantages and valuable features, which will be apparent from the description hereinafter given.

In the drawings, Figure l is a sectional elevation of my feed-water heater and purifier; Fig. 2, a plan thereof, and Fig. 3 a sectional plan on line 3 of Fig. l.

My device comprises any suitable shell or casing 1 of the desired shape and dimensions and divided by partitions 2 and 3 into three separate chambers intercommunicating, as hereinafter explained. The lowest chamber 4 is the expansion and oil-separating chamber and is located below what I will term for a whole and for convenience the filteringcham ber 5. The third chamber 6 is the heating and settling chamber and is located above the other two.

A suitable pipe or passage 7 extendsfrom the expansion-chamber upward into theheating-chamber and communicates only with the latter. This pipe extends a suitable distance above the normal high-water line, predetermined in a manner to be described.

The filter-chamber is subdivided by vertical transverse partitions 8 and 9 into three chambers, thel'chamber l0 being a receivingchamber for the water before filtration, chamber 1l the filter-chamber proper, and Vcham'- ber 12 the purified-water chamber,from which the water is drawn through pipe 13 by pumpsuction or otherwise. The partitions 8 and 9 have suitable perforations or passages 14 and 15, respectively, and chamber ll is supplied with any suitable filtering material.

The pipe 16 is the cold-water inlet, entering the casing above the highest normal Waterlevel and provided with a valve device 17,

operated in the well-known manner by a iloat 6o in a case 18, so as to maintain a normal water-line in the heating-chamber.

Supported within the heating-chamber bclow the water-inlet I arrange a suitable deflecting vessel or plate 19, preferably circular or umbrellashaped, so as to provided a circular shower around the pipe 7. The heating-chamber preferably has a suitable manhole 20.

The heating-chamber communicates with 7o the expansion-chamber through pipe 7 and by a passage 21 with chamber 10, into which also enters the condensation-return 22 for the condense-water of a steam-heating system.

A discharge-pipe 23, which is in connection with the sewer or other discharge-point, is arranged extraneous of the heater and communicates with the heating-chamber by overflow branch 24, above theA normal Water-line,

and by blow-off branch 25, substantially at 8o the bottom of the chamber. The chamber 10 also communicates with the pipe 23 by a blowoff pipe 26. These blow-offs are governed by suitable valves 27 and 28, respectively. The

expansion and oil-separating chamber likewise communicates with the discharge-pipe 23 by a branch or oil-outlet 29.

The operation of my device as thus far described and with a single water-line is as follows: Cold water is admitted by opening 9c the valve 30, and the flow will continue until the predetermined water-line is reached and maintained in the heater-chamber. Exhauststeam enters the chamber 4 through the inlet 3l, whereupon it is deiiected downward and 95 shower, which runs continuously so long as Iovo the feed-water is being used. Most, if not all, of the exhaust-steam is condensed and falls in the chamber. What may not have been condensed passes out through the outlet 33. The pipe or passage 2l projects above the bottom of the chamber, so as not to draw off sediment that settles therein. The water is thus drawn ott' into chamber I0, also fed by the pure condense-water from the return 22. If the heating system is in operation and if the lowest radiator is above the normal water-line, the water then passes through the perforations into the filter-cham ber ll, where it is properly filtered. It thence enters the chamber l2 in a purified condition.

The water-line maintained as above described, which I have designated by the line a a, is the one that may be used in summer or if the lowest radiator is above that line; but, as frequently happens, such radiator is below, so that the water-line must be lower when the heating system is in service. This lowering of the water-line is accomplished as follows: A second float-valve device 34, having a connection entering the intermediate chamber 5 and operating a valve in a coldwater inlet 35, maintains the water-line in the intermediate chamber and below the partition 3. Of course there is water in the heating-chamber of a depth equal to the height of the pipe 2l, as shown in Fig. 1, and water overflows therethrough when the level below in the intermediate chamber is lowered. It will be understood the other water-inlet is closed when the inlet 35 is opened. By these means I am able to obtain and maintain different water-lines, as desired, for the special purpose specified or for any other purpose.

In my device the exhaust-steam enters below both the other chambers, and the heat thereof is utilized to its fullest extent. The intermediate chamber is located adjacent to the expansion-chamber, and the water therein is highly heated just prior to its withdrawal for use. Likewise in passing through the large pipe 7 considerable heat is communicated to the intermediate chamber and to the body of water in the settling-chamber. Such novel arrangement of chambers is thus of advantage in the practical operation of feed-water heaters and purifiers.

In a feed-water heater, thecombination of a water-holding chamber, a water-inlet therefor, a steam-chamber having a steaminlet, and a steam pipe or passage therefrom into the water-chamber, and a third chamber intermediate of the other two chambers and surrounding such steam-pipe, means of communication between the water-chamber and the intermediate chamber, an outlet from said latter chamber, and means for maintaining a predetermined water-line in the Waterchamber.
